ing one end of eachoi' two separate lamps through one bridge-piece or support to one pole of the electric circuit.- The socket d has fixed; formed, or mounted therein the semicircular boss or web (1 this latter being advantageously cast integrrlly with said socket or tubular piece (1, the outside formation of said boss or web (1* being approximately of the inner contour of the reflector, so as to bed or fit snugly therein, and is secured thereto by. passing the screw g from the outside of the reflector 11 through the said web or boss (i and tube (1 into or against the insulating split washer e, which latter is thereby firmly pressed onto the barrel f of theplunger, and the whole of these parts are thus firmly'locked in position. The passage 71, may be drilled or otherwise formed through'the web d, as shown'in Fig. 2, to

a hole in the hollow head) to the aforesaid plunger.

In carrying out this invention I advantageouslyemploy straight tubular lampsi. e.., with' straight cylindrically shaped glass-withone (or' more) filament passing through said lamp from end to end, either straight through or otherwise, as desired, but in all cases with the electricalconnection to one end of said filament (or each filament, if-more than one) located at one end of the lamp and the electrical connection to the other 'end of said lamp located at the other end of. said lamp; and this character of lamp for the sake ofbrevity I have termed-and shall hereinrefer to' as a double-ended lamp, and, furthermore, in carrying out my desired to have the line of light. not only continuous throughout the length of the reflector a but also as straight as possible in each individual lamp mounted insaid reflector a, therefore to facilitate or attain this object I may employ a spring or springs in each lamp arranged to act ,upon or in conjunction with the carbon filament in such wise as to tend to keep said filament in a strai ht line or as near a straight line as possible uringincandescence-for instance, a spring connection such as shown at z in Fig 5-and, furthermore, I am enabled by my invention to maintain the filament of each lamp and every part throughout the length thereof constantly in focus of the reflector, or approximately so. v Y

m a: are the double-ended lamps as and for thepurposes'hereinbefore set forth. It will thus readily be seen that any double-ended lamp 1: can be placed inposition'in or removed from the reflectorby placing one end of same in the socket against the movable part f of the plunger and forcing the said mdvable part f into its barrel f until the other endof the double-ended lamp can pass into (or in the case of removing pass out of) the socket opposite thereto in the next adjacent bridge-piece.

In Figs. 5 and 6 I have illustrated a modified arrangement of socket or holder in which to mount the double-ended lan'ips w, as fol- .lows: The two spring contact-pieces 7'. 1?,

carried on the plate i, which is firmly attached to the reflector a and insulated therefrom in any suitable manner-as, for instance, by the means shown 1n the drawingscons1sting of a block of insulating material j, adapted to fit the inside of the reflector a, and through which passes a barrel or bush 1 ofiinsulating material to the exterior of the reflector a, and through this barrel 1' and also through the plate i is passed-a screw or bolt m with nut and washer n screwed .on the inside end thereof, and thereby the said plate i and spring contact-pieces 'i. i" are firmly held in position. Electrical connection is made from the conductor in one of the headed to said plate & and spring contact" pieces i i*, so that when the end of a lamp has been placed in position and clipped and heldby the COIltflCiFPlGCB 'L and the end of another lamp held in the spring contact,- piece 0?, thereby each double support or doule holder will connect one end of each of these two lamps to one pole of the electric circuit and similarly with the other double supports or double holders throughout the length of said reflecton In the construction illustrated in Figs. 5 and 6 any suitable removable cover or shield may be employed, if desired, overthe bridgepieces & i i For instance, an arched plate, such as w, may be clipped on the bead b or be 7 otherwise suitably secured and may advantageously be insulated onthe inside thereof.-

In the arrangement shown in Fig 2- the v lamps would have their contacts only cen tion of a concave trough-shaped reflector Having now described my invention, What I claim as new, and desire to secure by Letters Patent of the United States, is

1. In an illuminating device, the combinehaving an integral bead extending along each side edge, electric lamps supported on said reflector, and conducting-wires housed within said beads of the reflector and connected to said lamps. l

2. In an illuminating device, a support for double-ended incandescent lamps, comprising two contact members in close proximity to each other and having oppositely-disposed contact-surfaces to contact with different lamps, one of said members being slidable with respect to the other, and means tending to separate said members.

3, In an illuminating device, a support for double-ended incandescent lamps, embody- 1 its ing telescoping contact members, and a spring inclosed by and tending to separate said members.

4. In an illuminating device, a support for double-ended incandescent lamps, comprising a tube-section, an insulating-Washer held in said section, and a plunger mounted in said washer, said plunger embodying a barrel fixedly mounted in said washer, a movable part slidable in said barrel, and a spring in terposed between said barrel and said movable part, the barrel and movable part of said plunger being provided with oppositely-disposed contact-surfaces.

In witness whereof I have hereunto set my hand in presence of two witnesses.
